Is the problem much more noticeable when the car is at idle? Double check that Alternator output. 70 amps is not high output, and if the problem is especially noticeable at idle, it's probably due to the alternator putting out lower voltage( a common thing with alternators). Also, with that much draw from your sub amp, the wire from battery to alternator should be beefed up, as well as the ground wire from battery. You can make up your own cables by purchasing the wire to length and wire lugs at a local Welding shop, 4 gauge from alternator to battery is good. High output aftermarket Alternators shoot into the 200 amp range.
